The Healthy Functions Of Cortisol
Your cortisol levels naturally fluctuate throughout the day. They are generally highest when you first wake up, and then they go back down as the day goes on.
Although cortisol is often thought of in a negative way, having the right amount is a vital part of many bodily functions, such as:
-
controlling blood sugar levels
-
mood swings, anxiety, or depressive symptoms
-
excess body hair and irregular periods in women
-
low sex drive and erectile dysfunction in men
Having too much cortisol has also been associated with overall weight gain. This is because it can slow down your metabolism, increase your appetite, and change the way your body controls blood sugar.
Solutions To Better Balance
One of the more effective ways to control stress is to catch it early. When stressors appear, take a walk, meditate, practice breathing exercises, and/or find someone to talk to with whom you can address the stress-producing circumstances. Lets face it, its hard to detach from a stressful life. With regular exercise, sleep, and a healthy diet, we can be more prepared to manage the stressful situations, and we can prevent stress from aggravating our health.
Our history, experiences, and our perception, can have a tremendous influence on how each person deals with stress, said Halliday. How one experiences stressful events is influenced by the support one has, an individuals mental state, personal insight, and ones environment. A change in environment, shift in perspective along with healthy physical habits can stave off stressors that can lead to chronic health conditions.
How To Balance Cortisol Levels And Relieve Your Symptoms Of Chronic Stress
Cortisol is essential to health. Our bodies normally produce cortisol throughout the day in a cyclemore in the morning as we wake, less in the evening to prepare us for sleepto support our daily physical and emotional well-being. But when cortisol levels become higher or lower than normal for prolonged periods, that wellbeing can be severely compromised.
When were chronically stressed, our bodies maintain excessive levels of cortisol throughout the day. After months or years, elevated cortisol can cause serious problems across the bodys many systems. It can also lead to a suppressed HPA axis, formerly known as adrenal fatigue, where one can produce too little cortisol, which brings its own set of challenges and may require a variety of therapies to resolve. But by learning how to balance cortisol levels naturally and seeking the right care when needed, you can enjoy a calmer and healthier life.

What About Low Cortisol Levels
Itâs also possible to have extremely low cortisol levels, which can be caused by a dysfunction of the pituitary or adrenal gland. This is referred to as Addisonâs disease, and the lower cortisol levels associated with this condition can lead to symptoms like dizziness upon standing, fatigue, weight loss, mood changes, muscle weakness, and darkening areas of the skin.
When Should I See My Doctor About My Cortisol Levels

If you experience symptoms of Cushings syndrome or adrenal insufficiency, contact your healthcare provider.
If youre concerned about your daily stress levels, talk to your provider about steps you can take to minimize your stress and stay healthy.
A note from Cleveland Clinic
Cortisol is an essential hormone that impacts several aspects of your body. While there are several things you can do to try to limit your stress, and therefore manage your cortisol levels, sometimes having abnormally high or low levels of cortisol is out of your control.
If you experience symptoms of high or low cortisol levels, such as weight gain or loss and high or low blood pressure, respectively, its important to contact your healthcare provider. They can run some simple tests to see if your adrenal glands or pituitary gland are responsible for your symptoms.

How Can Nutritional Supplements Support Your Adrenal Glands
- High-quality vitamins and minerals help support a healthy metabolism and hormonal balance, which contribute to adrenal health. Our Essential Nutrients, with 30 vitamins and minerals, is an easy-to-take formulation that builds a strong nutritional foundation.
- Specific herbal supplements, such as astragalus root and eleuthuro , are effective at reducing the negative side effects of stress. Others, such as passionflower, produce calming effects and encourage sleep. Many of these herbs are found in our natural formulations Adaptisol and Serinisol.
How To Know If Your Cortisol Levels Is Too High
Unfortunately standard tests of adrenal function arent very helpful. If your primary care practitioner calls for a typical laboratory cortisol test, it will be difficult to see anything more than the most severe cases of adrenal dysfunction, such as Addisons disease or Cushings syndrome.
We recommend finding a practitioner who is willing to do salivary cortisol testing, which measures cortisol levels and a hormone called DHEA throughout the day.
A lab test isnt necessary to determine if you have adrenal fatigue or high cortisol, however. You can simply check in with how you feel. If your energy level is verylow in the morning but seems to increase right around the time everyone else is getting ready for bed, your cortisol cycle is probably out of whack. Its a good indication that you will reap huge benefits by taking steps to rebalance your adrenal glands.

The Symptoms Of Cortisol Imbalance
In todays modern high-stress world, high cortisol has become an increasingly common health concern. When high cortisol becomes a chronic issue, symptoms can include:
- Depression, anxiety, and irritability
- Difficulty concentrating
In the most severe cases, elevated cortisol can contribute to obesity, infertility, bone loss, and insulin resistance leading to type 2 diabetes. The good news is that a combination of diet, lifestyle changes, and medication can often help get your hormones back on track. Its important to note that the remedies mentioned here are commonly recommended to those who experience symptoms from excess cortisol due to lifestyle stress rather than a medical condition.
Its also critical to mention that after prolonged exposure to elevated stress, HPA axis suppression can cause the body to produce too little cortisol, which also disrupts healthy function. Symptoms of HPA axis suppression/adrenal fatigue include:
This condition is usually mild and can typically be treated using the same strategies as you would use to address high cortisol. The goal for both conditions is to balance.

Circadian Rhythm And Cortisol
Your sleep-wake cycle follows a circadian rhythm. Every 24 hours, roughly synchronized with nighttime and daytime, your body enters a period of sleep followed by a waking period. The production of cortisol in your body follows a similar circadian rhythm.
Cortisol production drops to its lowest point around midnight. It peaks about an hour after you wake up. For many people, the peak is around 9 a.m.
In addition to the circadian cycle, around 15 to 18 smaller pulses of cortisol are released throughout the day and night. Some of those smaller bursts of cortisol correspond to shifts in your sleep cycles.
What Are Signs Of Stress At A Glance

Why do high cortisol levels make you ill?
Stress is your bodys reaction to situations that it perceives as a threat. It releases the stress hormones adrenaline and cortisol, thereby increasing blood pressure, pulse and breathing rate, among other things. With chronic stress, the stress hormone levels are also constantly elevated. This upsets the bodys functions, affecting the cardiovascular system, digestion and psyche in particular.
What are the common signs of chronic stress?
Signs of chronic stress occur all over the body. Acute symptoms include digestive problems such as stomach pain and diarrhoea, skin rashes and acne, headaches, back pain as well as exhaustion and sleep problems.
Possible long-term consequences of chronic stress are an increased risk of cardiovascular diseases, obesity, type 2 diabetes and poor concentration. Mental illnesses such as depression and anxiety disorders can also occur.
What can I do about stress symptoms?
Some consequences of stress should be treated by a doctor for example, high blood pressure, depression and chronic skin changes.
Otherwise, it is of course worthwhile counteracting stress as the cause of the symptoms. You should therefore introduce stress management techniques in your everyday life, such as relaxation techniques, physical activity and socialising.

Can High Cortisol Cause Insomnia
High cortisol levels later in the day and near your bedtime trigger insomnia and other sleep problems. Thatâs because cortisol is an alertness-boosting hormone. While itâs great for helping you feel awake in the morning and alert throughout the day, too much cortisol circulating in your system too close to bed means youâre too wound up for sleep itself.
Effects Of Too Much Cortisol
While a short-term stress response can be beneficial, a prolonged response can have negative impacts on the body. Too much cortisol over an extended period of time can lead to fatigue, obesity, and other medical conditions like cushions disease. Below is a summary of medical conditions that can result from dysregulation of cortisol.

What Happens When You Produce Too Much Or Little Cortisol
The body usually produces the right amount of cortisol. In a condition such as Cushings syndrome, it produces too much. In a condition such as Addisons disease, it produces too little.
Symptoms of too much cortisol include:
- weight gain, particularly around the abdomen and face
- thin and fragile skin that is slow to heal
- for women, facial hair and irregular menstrual periods
Symptoms of not enough cortisol include:
If you experience any of these symptoms, your doctor may suggest you have a blood test to measure your cortisol levels.
How Does Cortisol Affect Sleep
Healthy amounts of cortisol at the right times help transition you into wakefulness in the morning and fall asleep by your target bedtime. Ill-timed cortisol production disrupts your sleep-wake cycle so that you have trouble falling asleep and staying asleep, while missing out on the alertness-boosting effect of the cortisol awakening response in the early morning. This leads to a vicious cycle of excess cortisol and sleep loss.

Signs Of Chronic Stress
Stress becomes harmful when it doesnt abate. Before you know it, we get caught up with it, we dwell on it, and it is prolonged. We all have stress, said Tina Halliday, LCSW, behavioral sciences manager and CAT admissions coordinator for University of Utah Health. Stress can be produced from unpleasant situations as well as great situations like getting a new job, moving into a new home, or even falling in love.
There are a variety of different feeds that create stress. One example that is notable is related to your thought process, how we perceive an experience, said Halliday. Our minds can create stress. Halliday likens chronic stress to an everyday experience: like peeling out every time a red light turns green. You are over using a response that is not necessary to the situation every time a light turns green, hence leading to unnecessary wear on the vehicle. This is similar to our responses and perceptions to stress producing events. Can some of those events be managed in a way that brings them down to size and does not produce unnecessary wear on an individual? Back to our car analogy, if you can accelerate from a full stop in a more gradual way, its going to be much better on your engine in the long run. Halliday said.

The Autonomic Nervous System
The autonomic nervous system is part of your body’s nervous system and is made up of:
- The sympathetic nervous system , also known as the fight-or-flight response
- The parasympathetic nervous system , commonly known as the rest-and-digest or feed-and-breed response
The ANS works in tandem with the HPA axis to react to external stressors. But, what exactly is the HPA axis?
What You Can Do To Reduce Cortisol Levels

The first step is to consult a medical professional.
If you suspect you may have high cortisol levels, its important to see a healthcare provider, as they can order a blood test to measure your cortisol levels, Dr. Dlott states. Since symptoms of high cortisol can also be associated with other conditions and health issues, its important to get confirmation on what is or is not causing your symptoms.
Once you find out the source of high cortisol, you can take steps to treat it.
Methods for reducing cortisol levels depend on the root cause, Dr. Dlott explains. For Cushings syndrome, youll typically need medical interventions like medication and/or surgery. However, finding ways to manage stress levels, eating a balanced diet, exercising regularly and making sure youre getting enough sleep can have a positive impact on managing cortisol levels as well as your overall health.
Dr. Trent Orfanos, MD, ABIHM,Director of Integrative and Functional Cardiology, agrees that sleep, exercise and healthy eating habits are essential.
Finally, do your best to practice stress management, whether its through meditation, breathing exercises, or whatever works for you. Dr. Orfanos recommends this Heart Math exercise:

How Cortisol Works In The Body
Before diving into the signs that your cortisol levels are too high, its helpful to understand the way this hormone should be working.
Cortisol is a hormone produced in the adrenal glands. It fluctuates naturally during the day and night for example, most people tend to hit their highest cortisol level in the morningwhich helps get you going after waking upand the level gradually tapers through the day until it reaches its lowest level right before bed. Thats when de-stress hormones like melatonin surge to help you fall asleep.
So what does cortisol actually do? According to Cleveland Clinic, cortisol affects almost every organ and tissue in your body, playing a major role in helping control your metabolism, , reducing inflammation, and keeping blood sugar levels steady.
Although cortisol follows a natural pattern of peaks and dips, external factors can cause cortisol to surge. If you need to leap out of the way of an oncoming car, for example, your body will spike your cortisol level to provide an energy jolt for that action, part of your fight or flight response. But stressors that are ongoing can keep your cortisol high, and that is often a problem.
You Experience Backaches And Headaches
When your cortisol levels are high over a long period of time, your adrenal glands start to get depleted. This raises prolactin levels, increasing the body’s sensitivity to pain such as backaches and muscle aches. Excessive cortisol has also been shown to shrink parts of the brain such as the hippocampus, and it could spur migraines.
